Improvement in coal-oil stoves



UNITED STATES PATENT OFFICE.

ARTHUR RASCHKE AND ALLEN H. JONES, OF CLEVELAND, OHIO.

IMPROVEMENT IN COAL-OIL STOVES.

Specification forming part of Letters Patent No. 179,865, dated July 18, 1876; application tiled June 13, 1876.

To all whom it may concern:

Be it known that we, ARTHUR RASCHKE and ALLEN H. JONES, of Cleveland, in the county ot' Cuyahoga and State ot' Ohio, have invented a certain new and Improved Coal- Oil Stove; and we do hereby declare that the following is a full, clear, and complete description thereof, reference being had to the accompanying drawings, making a part of the same. Y

Figure l is a sidev elevation of the stove. Fig. 2 is a plan view. Fig. 3 is a vertical transverse section. Figs. 4 and 5 are two views of a detached section.

Like letters of reference refer to like parts in the several views.

The nature ot' this invention relates to an oil-stove; and the object of the vsame is to provide a certain and convenient device to raise or depress the wick for regulating' the heat, the heating-section of the stove being similar to an Argand lamp, possessing a cylindrical wick-tube and burner.

The construction of the invention and the' operation of the same are substantially as follows:

In the drawings, A represents a reservoir" for holding oil, supported on the legs B. In the center of the reservoir is secured a wicktube, B', consisting ot` an inner and an outer shell, C D, Fig. 3, forming a narrow annular chamber, a, Fig. 2, for the accommodation of a wick. (Indicated by the dotted line b in said Fig. 2, also seen in Fig. 3.) E is the crown ot' theV wick-tube; and F, a chimney, with glass lights b.

To raise or lower the wick in the tube is the purpose of this invention, which is accomplished by an adjustable ring, G, Fig. 3, a detached View ot' which is shown in Figs. 4 and 5. Said ring is tted in the annular space or chamber a referred to, which, together with the wick, lills the space, and whereby the wick is adjusted in the tube byY means ot' a screw, H, attached to the ring by an arm, l, holding a nut, c, through which the screw passes, as will be seen in Fig..3.

That the arm may move the wick in the tube, a slot is made in the outer shell D thereof', through which the arm passes to the screw, and wherein it slides vertically for adjusting the Wick on being actuated by the screw, which is manipulated by a inger-piecc, J. The bottom of the annular chamber holding the wick is closed, and is supplied with oil from the reservoir by a tube, K, Figs. l and 3.

To prevent the escape of oil to the outside through the slot in which the arm I slides, the slot-arm and screw areinclosed in an oil-tight case, L, as shown in Fig. 3. rIhe upper end otn the case may or may not havev a direct and open communication with the reservoir for supplying the wick with oil, which it can do4 through the slot.

From the above description ot' the stove it will be obvious that on turning the screw in the proper direction the arm and ring will be drawn upward, and therewith the wick, which should be placed around it. The sharp points of the pert'orations d, Fig. 4, will push the wick upward or downward, as the case may be, and thus produce a larger flame at the burner, for heating' or for extinguishing the same.

M, Fig. 3, is a deflector, which may be raised more or less above the end of the wick-tube,

to dcector spread the flame. Said deector is secured in position in the air-passage N by an inverted cone, M, to the hase of which the deector is attached.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. The ring Gr, nut c, screw H, and case L, arranged in relation to, and in combination with, the wick-tube B and reservoir'A, substantially as described, and for the purpose set forth.

2. The deflect-or M and inverted cone M', in
